Blender's features include 3D modeling, UV unwrapping, texturing, raster graphics editing, rigging and skinning, fluid and smoke simulation, particle simulation, soft body simulation, sculpting, animating, match moving, rendering, motion graphics, video editing, and compositing.
The Persistence of Vision Ray Tracer, most commonly acronymed as POV-Ray, is a cross-platform ray-tracing program that generates images from a text-based scene description. It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins for Amiga computers. There are also influences from the earlier Polyray raytracer because of contributions from its author, Alexander Enzmann. POV-Ray is free and open-source software, with the source code available under the AGPL-3.0-or-later license.
X3D is a royalty-free ISO/IEC standard for declaratively representing 3D computer graphics. File format support includes XML, ClassicVRML, Compressed Binary Encoding (CBE) and a draft JSON encoding. X3D became the successor to the Virtual Reality Modeling Language (VRML) in 2001. X3D features extensions to VRML, the ability to encode the scene using an XML syntax as well as the Open Inventor-like syntax of VRML97, or binary formatting, and enhanced application programming interfaces (APIs).
Crystal Space is a framework for developing 3D applications written in C++ by Jorrit Tyberghein and others. The first public release was on August 26, 1997. It is typically used as a game engine but the framework is more general and can be used for any kind of 3D visualization. It is very portable and runs on Microsoft Windows, Linux, UNIX, and Mac OS X. It is also free and open-source software, licensed under the GNU LGPL-2.0-or-later, and was SourceForge.net's Project of the Month for February 2003.
Irrlicht is an open-source game engine written in C++. It is cross-platform, officially running on Windows, macOS, Linux and Windows CE and due to its open nature ports to other systems are available, including FreeBSD, Xbox, PlayStation Portable, Symbian, iPhone, AmigaOS 4, Sailfish OS via a QT/Qml wrapper, and Google Native Client.
Inkscape is a free and open-source vector graphics editor used to create vector images, primarily in Scalable Vector Graphics (SVG) format. Other formats can be imported and exported.
Reyes rendering is a computer software architecture used in 3D computer graphics to render photo-realistic images. It was developed in the mid-1980s by Loren Carpenter and Robert L. Cook at Lucasfilm's Computer Graphics Research Group, which is now Pixar. It was first used in 1982 to render images for the Genesis effect sequence in the movie Star Trek II: The Wrath of Khan. Pixar's RenderMan was one implementation of the Reyes algorithm, until its removal in 2016. According to the original paper describing the algorithm, the Reyes image rendering system is "An architecture for fast high-quality rendering of complex images." Reyes was proposed as a collection of algorithms and data processing systems. However, the terms "algorithm" and "architecture" have come to be used synonymously in this context and are used interchangeably in this article.
Mesa, also called Mesa3D and The Mesa 3D Graphics Library, is an open-source software implementation of OpenGL, Vulkan, and other graphics API specifications. Mesa translates these specifications to vendor-specific graphics hardware drivers.
XWiki is a free wiki software platform written in Java with a design emphasis on extensibility. XWiki is an enterprise wiki. It includes WYSIWYG editing, OpenDocument based document import/export, semantic annotations and tagging, and advanced permissions management.
Poppler is a free software utility library for rendering Portable Document Format (PDF) documents. Its development is supported by freedesktop.org. It is commonly used on Linux systems, and is used by the PDF viewers of the open source GNOME and KDE desktop environments.
Pixie is a free, photorealistic raytracing renderer for generating photorealistic images, developed by Okan Arikan in the Department of Computer Science at The University of Texas At Austin. It is RenderMan-compliant and is based on the Reyes rendering architecture, but also support raytracing for hidden surface determination.
Synfig Studio is a free and open-source vector-based 2D animation software. It is created by Robert Quattlebaum with additional contributions by Adrian Bentley.
Freestyle is a free, open source renderer for non-photorealistic line drawing from 3D scenes.
LuxCoreRender is a free and open-source physically based rendering software. It began as LuxRender in 2008 before changing its name to LuxCoreRender in 2017 as part of a project reboot. The LuxCoreRender software runs on Linux, Mac OS X, and Windows.
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a Wayland compositor, because it additionally performs the task of a compositing window manager.
Orx is an open-source, portable, lightweight, plug-in-based, data-driven and easy to use 2D-oriented game engine written in C.
GTK Scene Graph Kit (GSK) is the rendering and scene graph API for GTK introduced with version 3.90. GSK lies between the graphical control elements (widgets) and the rendering.
Natron is a free and open-source node-based compositing application. It has been influenced by digital compositing software such as Avid Media Illusion, Apple Shake, Blackmagic Fusion, Autodesk Flame and Nuke, from which its user interface and many of its concepts are derived.
RenderDoc is a free and open source frame debugger that can be used to analyze single frames generated by other software programs such as games. RenderDoc can provide in-depth analysis of single frames from any application that uses Vulkan, D3D11, OpenGL & OpenGL ES, or D3D12. RenderDoc also allows the user to manipulate a captured frame to inspect different things such as pipeline stage, commands, texture maps, models, assets, and more. RenderDoc can also capture assets outside the view of the game's camera. RenderDoc supports analyzing frame rendering costs on the graphics processing unit.
